In the Igf-2 allele, which chromosome is imprinted? Which is expressed?
Match the following terms with their descriptions below.
If a cell is fused with another cell, which of the following would be the best example of a trans-mechanism of epigenetic control?
Answer: A gene that is originally silenced in one cell but expressed in the other is silenced in the hybrid.
I hope this helps, Regards.
The trans-mechanism of epigenetic control can result from the fusion of cells, as seen when certain diets in mice alter DNA methylation. An example of gene imprinting, another form of epigenetic control, is seen in the Igf-2 allele where the paternal allele is expressed and the maternal allele is silent.
The fusion of cells can lead to a specific type of epigenetic control, termed trans-mechanism. This process is best exemplified in the case of the pseudoagouti offspring phenomenon in mice. When female mice are fed a specific diet, it alters the methylation processes of their DNA. As a result, a specific region in the agouti gene becomes hypermethylated which in turn leads to an increased proportion of pseudoagouti offspring.
Addressing the second part of your question, in the Igf-2, or the Insulin-like growth factor 2 gene, it is the paternal allele that is usually expressed while the maternal allele is imprinted and silenced. Imprinting is another form of epigenetic control where the activity of a gene is determined based on which parent the allele was inherited from.

O Foraging
O Nomadism
O Sedentarism
Answer:
Sedentarism
Explanation:
The result of agriculture is the transition from a nomadic lifestyle to a settled lifestyle.
Agriculture is the practice of cultivating plants and rearing animals for food, fiber, medicinal plants, and other products used to sustain and enhance human life. It had a significant impact on human societies, resulting in various changes.
One of the major results of agriculture was the transition from a nomadic lifestyle to a settled lifestyle. Before the development of agriculture, early humans relied on foraging and hunting for their sustenance. However, with the discovery of agriculture, people started cultivating crops and domesticating animals, which allowed them to establish permanent settlements.
This transition from nomadism to sedentarism was a crucial turning point in human history. It led to the development of permanent settlements, the growth of population, and the establishment of complex societies. With the ability to produce surplus food, people no longer needed to constantly move in search of resources. This stability allowed for the development of trade, specialization of labor, and the rise of social hierarchies.

Out of the following given choices;
Multiple Alleles
Chromosomes
Carriers
Sex-linked genes
The answer is multiple alleles. While we are used to diploid organisms like humans having two alleles (on same loci of each chromosome of homologous paired chromosomes) for a particular gene, it is thus the case there are two alleles in a population that determine a particular trait. However, there can be more than two alleles in a population that determine a particular trait. Individuals in the population may have different forms of the allele for the trait (please note that a diploid individual can still hold only two alleles). This, therefore, means that they are more than two alleles in the population that determine a trait such as coat/fur color (or blood type in humans). These are what are referred to as multiple alleles. The alleles interact with different degrees of dominance over others alleles hence the various phenotypes formed form their interaction.
